create a triangle in points (0,0) (0,100) (50,100)
the dimensions of the lines are 50 and 100
the including edge must be 30 degrees
but is 26.57 degrees! make the same in AutoCAD. Again it is wrong!
My computer does not know the sin30 function? [/img]
Top Noob is right. You just got your sides mixed up. The hypotenuse is 2x the opposite side. With the dimensions you gave, the angle would be what the system says.
